The notion that ordinary automotive pump gas can be a cheaper alternative to increasingly expensive avgas has had a rough time of it. Mogas gained traction during the 1980s and saw wide enough distribution to be a player, but a shrinking price Delta against avgas, a cold shoulder from the engine manufacturers and a rising flood of ethanol has stunted the mogas movement.
Now, a company called Airworthy Autogas wants to make another run at the market with a boutique blend of mogas designed to forthrightly address three complaints about pump gas intended for cars: lack of assured octane, a guarantee of zero ethanol and satisfying beefs raised by the engine manufacturers about both.
The critical piece of the mogas puzzle is price. Airworthy Autogas is sure its product will be cheaper than avgas, but it’s not sure how much cheaper and it won’t know that until production is stabilized and with a few months of history.
